Security made simple: RedPhone and TextSecure rolled into Signal for Android

If you want to make free, worldwide encrypted calls, then you should consider using Signal; it supports encrypted texting too.

While iPhone users have had the option to use Signal since last year, yesterday Open Whisper Systems founder Moxie Marlinspike announced that TextSecure and RedPhone have been rolled into one Signal for Android app.

Signal is so super easy to use, even your granny can make private calls and send private texts. Cryptography researcher Matt Blaze previously tweeted about overhearing an elderly gentleman explaining how to install Signal; Blaze called it a “turning point.”
